I don't have any notes, and it's been a while since I tried it.  To
the best of my knowledge, I loaded the UCM config from the ChromeOS
tree manually with alsaucm, then enabled/disabled headphones from
there.

https://chromium.googlesource.com/chromiumos/third_party/adhd/+/master/ucm-config/nyan/NVIDIA%20Tegra%20Venice2/

The important stuff is all in the enable sequence of HiFi.conf

Let me know if that helps.

Does playback appear to be working, except you can't hear anything or
does aplay fail?
